Объяснение:

Кроме обычных конструкций здесь есть еще 2 примечательные вещи: Предложения в повелительном наклонении и условные. Повелительное наклонение начинается с инфинитива ( то есть глагол, который дается в задании без окончаний или частички to) Например Иди к доске-Go to the blackboard

Подчиненные предложения времени и условия сложнее в образовании. Нужно найти главное и подчиненное предложение. Главное всегда употребляется во Future Simple, а подчиненное-в Present Simple. Например Мы покатаемся на лыжах, если погода будет хорошей. Мы покатаемся на лыжах (при каком условии?) если погода будет хорошей. Значит покатаемся-в будущем, будет хорошей- в настоящем. Получаем We will ski if the weather is fine
